Having a car accident on highway. This accident raises the concern about safety issue of Toyota Prius. One part of main battery cable underneath the car was not well protected or covered. When a solid objective right hitting the cable with blast sound , the cable was broken apart. , we lost all the power, the car totally was dead on the highway. We have 3 people in the car,my 85yr old mother,my wife and me. It is horrible.
I was driving with to passengers on the new jersey turnpike at 65 mph when I heard a loud noise from under the car. The plastic front engine cover had come loose and was dragging on the pavement. A aaa mechanic removed the part and the Toyota dealer is replacing it at not charge. I think it is a safety defect.
2010 Toyota Prius. Consumer writes in regards to rapid acceleration issues the consumer wants to know did the investigation into this matter examine the interrelationship between the accelerator, braking system and cruise control.
After approximately 4 oil changes the oil access door breaks off the vehicle. The oil has been changed 9 times in my Prius and after 4 oil changes the oil access door has now broken off twice. Each time I heard it break loose like I drove over some debris and I could see it in my rearview mirror go flying across the highway lanes. The oil access door does not have a hinge. It is all plastic and is bent/folded to gain access to the oil filter and drain plug. I changed the oil the first 4 times and the dealer complained I was doing something wrong. The dealer was reluctant to replace the entire engine undercover assembly, stating they would only do it one time. The dealer changed my oil the next 4 times and it happened again right before I scheduled my 5th oil change. After the second occurrence, I retrieved the oil access door to confirm since the vehicle is so low you cannot see it under the car unless it is raised up.
Dear sir or madam, a few days ago I found abundant evidence of mice activity in the cabin of my 16 month old Toyota Prius. After some internet research I found out that this is unfortunately an extremely common problem with Prius model cars and other Toyota models. The presence of rodents in the engine area is of course unavodiable but this is the first time I hear about the car design allow mice to easily move into the cabin. This obviously has severe consequences: I already have to replace the air filter and the padding behind the gloves compartment and I am not sure if any other parts have been chewed away. More importantly this is certainly a health and safety concern. I have to get the car detailed and the air system flushed to avoid toxic contamination from mouse excrements, and this endangers me every time I drive: a mouse crawling in the cabin of the car while I am driving is a major safety issue! it appears that the placing of screens in as few as 4 parts of the air system would stop the mouse access to the cabin, but Toyota, both my local dealer and the national service center, claim there is nothing the can or will do, and that, despite the abundant evidence to the contrary, this is a normal occurrence in all cars. Many people have posted online about mice and rodents in their Prius cars. A feel this is a major safety issue with the car, and I am extremely disappointed that neither the local dealer nor the Toyota corporate services are willing to helo me solve this situation and prevent it from happening again. I think the consequences of this design defect should be covered under the warranty and Toyota should design a scree part to cover the vents where necessary to prevent this from happening in the future.
2010 Toyota Prius-while approaching stop light with brakes slightly engaged, left front tire struck a pot hole approximately 15" in diameter and two pavement layers deep. Vehicle brakes got soft and car accelerated briefly for less than one second. Braking then returned to normal feel and acceleration ceased.
Gas pedal does not accelerate when foot goes down on it 4 times -- I do not have exact dates 1. Early November, 2010 1 incident 2. January, 2011 2 incidents 3. Unknown unknown 1. Coming down the 405 at the 101 interchange, my gas pedal did not propel my car forward. I coasted to the side, turned off the motor, started again and all was fine. I reported it by phone and got an appt. To have the car checked. The dealer said there was nothing wrong. 2. It happened again as I was coming down the 101 into camarillo. I stopped, restarted and went on my way. 3. It happened again but not on an incline. I was going about 10 miles an hour on a flat parking lot. Gas pedal did not respond and I created a traffic jam because I could only coast into the parking garage. Here are my notes regarding this problem made calls to Toyota corporate totally unresponsive- take it to dealer and leave it there or just consider it reported . There were calls to the dealer and corporate regarding 3 of the incidents. Toyota customer service the car was checked 3 times- once after the first incident and then the dealer brought in a company inspector - each time they found nothing wrong. They told me that the “box� showed 4 incidents. Have no idea what that means toyota’s answer is always the same-- that I am putting my foot on the gas pedal and the brake at the same time!! that is impossible to do unless one uses both feet. (I do not drive with both feet and I cannot put my foot on both pedals even if I wanted to) Toyota has not come up with a solution or acknowledged that there is a problem. I am worried that one day I will need to accelerate to get out of danger and the gas pedal will not respond again. There is something wrong with this car. Toyota does not accept that. They say it is driver error. Yet it's physically impossible for me to duplicate.
I was making a sharp right turn to pull into a parking space, slowing to a stop. The car suddenly and unexpectedly accelerated forward out of my control. I applied the brakes as hard as I could, with no response. As the car was racing into a tree, I shut off the engine by pushing the power button to off. The car knocked down a tree and came to a stop on top of it.
True! gear problem! remember airbus flipping our of control when they came out with fly by wire? the joy stick gear is default to shift into neutral when normal push bring it in to reverse. No way to put it in neutral. I thought the same thing & was in denial until I realize that its impossible to put it into neutral when thing is speeding out of control. Don't take it lightly- I did bought a 2010 Prius just now & realize - u can't put it - in neutral. I was in denial. Also, ventilator fan suddenly accelerates when u try to switch the modes.
Two occurrences: sudden loss of acceleration without any warning. First time dealership said it was a loose computer connection which they said they tightened and rebooted computer. Second occurence, they say they don't know what happened and have contacted Toyota headquarters for advice. Still waiting after 6 days. Concerned about this happening on a very busy freeway. We were on a highway that wasn't that busy and we were able to safely pull to the side of the road. Could be disastrous on a busy freeway where everyone is going bumper to bumper at 75 mph!!!.
When applying the brakes over a bumpy or metallic surface, there is a uncomfortable delay until the brakes "kick in". This has been going on for some time.
I was driving on pleasant grove blvd in roseville CA with a speed of 44 mph. It was about 7:16 pm. On my right a saw a black cat on the curb ahead of my walking, trying to make it's way across pleasant grove blvd. I made an emergency stop (didn't have to come to a complete stop) not to hit the cat. I pushed the brake pedal with full force in order to stop in time. There was no one behind me at the time happily. However, I noticed that the abs system didn't kick in and hence my brakes blocked shortly during the emergency stop. In la I had this happen twice to me that the abs didn't kick in and my wheels block. It's easily repeatable by making a stop that requires a short distance to stop. Happily this is hardly ever necessary, but I don't feel safe doing it. I have driven two Toyota corollas, they never had this issue and always the abs worked great. In the 2010 Toyota Prius, this doesn't work well. In addition to the braking issues on the highway, this is another problem with the Prius brake. It makes me feel insecure on the road with the Prius and I don't enjoy driving it due to these issues. It's just not safe!.
The 2010 Toyota Prius that I have has very grabby brakes when backing up. This usually occurs when backing out of a parked position. It is a recurrent problem and can repeatedly jerk the car to a fast stop when backing up. Such quick jerking can make one lose control of the car.
My 2010 Prius stops braking or accelerates when hitting a pothole or bump causing the car to stop later than anticipated. Almost hit a person in the cross walk.
Brakes disengage momentarily when braking on a rough or rippled surface. It gives the feeling the vehicle is being accelerated. Uncontrolled travel distance can be lengthly. I have experienced four such instances.
Since I bought my 2010 Prius I've experienced problems with the brakes. The car experiences a sudden surge of power when going over bumps or hitting potholes if the brakes are being applied at the time. This happens at any speed at any time of day, only when the brakes are being applied lightly. This problem occurs several times a week, always when hitting bumps, potholes or uneven pavement. It always is a sudden, very brief surge of power, sometimes enough to push me back into the seat. So far there have been no consequences other than very frayed nerves. I've reported this to my dealer who responded that the car was a new technology and I simply didn't know how to drive it properly. I learned in subsequent conversations directly with the mechanic that others had complained about this problem but they had no idea what was causing it. To date, the dealer has done nothing about it. The only thing that fixes the problem is to brake further from a stop or to roll over bumps before braking. I'm very concerned about a situation where I need to brake suddenly but the car surges, possibly causing a crash.
I've been hearing in the news about the potential of a braking issue with the 2010 Toyota Prius. Just wanted to let you know that I definitely noticed this issue in my new Prius. Approximately once a month, when I'm braking over an uneven or slippery surface, especially if it is only one side of the car going over the slippery surface, while I'm braking, there is a moment lasting less than a second where it feels like the brakes disengage. (causes your heart to skip a beat when it happens. ) I also noticed a separate quirk the other day that I want to pass on to you. I'm not sure if this was done deliberately by Toyota or whether this is a defect, however, I believe my speedometer is calibrated so that it reads a speed that is 2 mph faster than my actual speed. I noticed this when I went on a trip and used my wife's tom tom, which uses its gps signal to measure the speed of the car. The tom tom is usually spot on in my wife's Acura. In the Prius, it was indicating that my true speed was 2 mph less than what my speedometer indicated. I'm wondering if this wasn't somehow intentionally done by Toyota to get better perceived gas mileage by the driver. Having the car get over the 50 mpg threshold is a big marketing advantage for them. Getting over this threshold would be easier if the actual speed of the car was less than the perceived speed.
I have a 2010 Prius. When I go over small bumps while breaking, the brakes stop working and the car accelerates for a bit. Disconcerting.
My Toyota Prius 2010 (5000 miles) few times already has an "accelerator that goes wild", but luckily for me, I can hit the brakes. It happened only when I drive back from my garage.
I have owned a 2010 Toyota Prius for approximately six months. During that time I have experienced on several occasions (6-8 times) a feeling that the car is actually lurching forward while I am driving at low speeds over rough pavement and applying the brake. In my case the lurching of the car happens only when I am slowing down to make a turn. It is a frightening experience when you're applying pressure to the brake and your car feels as though it is about to take off. The sensation lasts for a second or two nevertheless it's still as I said frightening. When I first mentioned it to my local dealer the response was that it's the abs brakes and it's normal.
My 2010 Toyota Prius seems to lose braking power whenever I hit a bump or slick patch in the road. Not only do the brakes seem completely disengaged, but the car actually feels like it accelerates forward. I've adapted my driving, but only after I'd ended up in the middle of a couple of intersections because the car shot forward while I was ostensibly braking. Fortunately, I've not yet rear ended anyone.
The contact owns a 2010 Toyota Prius hybrid. The contact was driving 30 mph when he pulled the cruise control lever up to increase the speed, the steering wheel would turn left and when he pulled the lever down to decrease speed, the steering wheel would turn to the right. He took the vehicle to the dealer who advised him to hold the steering wheel tight when increasing or decreasing the cruise control speed and it would not move. The contact was concerned that he had to hold the steering wheel tighter than normal at all times. He called the manufacturer and was instructed to take the vehicle back to the dealer. When he took the vehicle back to the dealer, they informed him that the failure could not be duplicated. The failure mileage was 5. The current mileage was approximately 7,000. Updated 05/24/10 the consumer was told to have a firm grip on the steering wheel when using the cruise control to adjust or set the speed of the vehicle. The consumer stated the steering was affected whenever he adjusted the cruise control lever mechanism. Updated 06/01/10.
I bought a 2010 Prius in August 2009. When I apply the brakes on a bumpy road there is a loss of breaking for a short time. It feels like a surge in acceleration before the brakes work again. I do not know if it is a safety issue but it is very disconcerting.
1. I purchased this 2010 Prius in August 2010. I have experienced unanticipated acceleration two times since the last (initial) service. Once with my husband driving on route 17 and the other time while I was driving on a local road. 2. As I stated in my service paperwork when the car was first serviced, there is a problem with the brakes. They do not stop on uneven road surfaces, such as pot holes, bumps, etc. Your service department said that this is caused by the abs and it is ?normal?. Obviously there is still a problem. Please advise what will be done to correct this issue. 3. When start the engine first thing in the morning (or when the car has not been driven for a while) often, but not always, it makes a grinding noise when starting.
After pushing the power button and then shifting out of park to either drive or reverse, the vehicle lunges and I have to apply the brake, which makes the vehicle jerk. Sometimes the gasoline engine starts before I shift into gear sometimes it doesn't. This process is repeated over several times for a minute or so, then it corrects itself. I am just inching along lunging, braking, jerking. . . This has occurred about ten times over the eight weeks and 2540 miles since purchased August ll, 2009. Took to dealer, on sept. 29, 2009; they kept it for about 2 hours, could not duplicate and said all systems checked out ok. At that time the problem had occurred about six times. Since that date, this continues to happen intermittently. This has happened only when in my own drive or in parking lots. I am fearful that it could happen on the road and cause an accident and injury to myself and/or others. The dealer and Toyota case manager say that they must be able to duplicate the problem before anything can be done to correct it. Since it happens only on occasion, it will be difficult to duplicate.
This is the breaking problem i’m having with my 2010 Prius: when I am stepping on the break, and also go over a small bump in the road, the car seems to accelerate for a moment and then goes back to breaking again.
While braking on roadway that has a manhole or a patch in the asphalt that is not exactly level with the rest of the asphalt, the tires feel like there is no traction and the car feels like it is hydroplaning. I have experienced this while driving on two specific roads and now I try to avoid the areas to prevent the feeling of having no control over the car. It feels like the car lurches forward and has no traction. This happens on dry roads. It is very frightening when it happens. I first noticed it when I first purchased the car in July and it has continued to happen.
While braking and on uneven sufrace brakes feel like they have sropped working and then later catch, vehicle seems to actually speed up. It occures at lease 1+ a day depending on where I am driving and or weather conditiond. Speed dosn't always matter, as if coming off expressway and braking, speeds can be 55mph and it still happens. Luckily I have not hit any thing yet.
When breaking my 2010 Toyota Prius, if I go over a bump or pot hole, it feels like the brakes cut out and my car jolts forwards. It seems to happen only when I go over a bump or something that would shake the car a bit. Nothing has been done as of yet to correct the problem.
